The Sunday Times enjoyed the biggest circulation boost from Team GB's golden Saturday, with readers eager to read about the exploits of gold medal winners including Jessica Ennis and Mo Farah helping to add about 70,000 copies compared with a normal weekend.

Overall, the Sunday Times, its News International stablemate, the Times, and Associated Newspapers titles the Daily Mail and Mail on Sunday have added the most sales so far during the London 2012 Olympics, according to unofficial industry estimates.

Most other national titles have enjoyed small gains. However, the Sun, Daily Star and their Sunday editions have seen their circulation dip during the Olympics.

At the weekend the Sunday Times added about 71,000 sales the day after Team GB won six gold medals – including three in athletics in 45 minutes in the evening for Ennis, Farah and Greg Rutherford.

A rough estimate puts News International's quality titles as up well over 5% compared with their average sales for the 10-day period.

These unofficial figures are based upon the typical average sale of each national newspaper title, stripping out boosts from marketing activity such as TV ads and print promotions.

The Times Sunday Times have cumulatively put on a total of just over 300,000 sales in the 10-day period from Saturday 28 July up to and including Monday 6 August. The Sunday Times has contributed about 114,000 of those extra copies.

Associated's Daily Mail and Mail on Sunday have added almost 240,000 copies across the 10-day period, according to unofficial sales estimates.

The Daily Mail added 66,000 copy sales on the Saturday following the opening ceremony, second only to the Times and its best performance of the week. The Mail on Sunday added 49,000 at the weekend.

Overall the Mail titles are up almost 1.5% over a typical 10-day sales period.

However, the Sun, including the Sunday edition, and the Daily Star, including the Daily Star Sunday, have fared the worst among all national newspapers so far during the London Olympics.

The Sun has lost almost 150,000 sales with the biggest slumps coming on Sunday 29 July, with a sales drop of more than 60,000 copies, and last Saturday when almost 50,000 copies less than usual were sold.

Similarly Richard Desmond's Star is estimated to have lost more than 110,000 sales, although the dip has been spread more evenly with most days so far down up to 20,000 copy sales.

Most of the other quality and mid-market titles did well, particularly given that the trend is for sales decline during the August summer holiday period, with sales up between about 30,000 and 50,000 for the 10-day period.

Telegraph Media Group said that sales of the Daily Telegraph and Sunday Telegraph combined were up about 200,000 cumulatively over the period.

The Daily Mirror and Sunday Mirror's circulation has pretty flat across most of the Olympics.

However the Sunday Mirror managed an uplift of almost 60,000 at the weekend, ensuring an overall uplift of just over 50,000 for the 10-day period.

The Guardian, which also publishes MediaGuardian, started the Olympics well with an uplift of about 20,000 on the Saturday after the opening ceremony.

Across the period sales, including those at the Observer, were up about 1% or almost 40,000 copies over a typical period.

The Daily Express and Sunday Express are up about 20,000 copies; while the Independent and Independent on Sunday, are up about about 10,000, as is stablemate i.
